Study on Data Breaches • Verizon conducts an annual study of data breaches • The US Secret Service and Dutch High Tech Crime Unit provided the results of their data breach efforts which Verizon combined with their results • The study does not include cost analysis of data breaches, but rather, high-level analysis of root cause and perpetrator
How did we arrive here? Individual card brands maintained their own security and compliance programs for merchants, processors, inc. • VISA Cardholder Information Security Program (CISP) • MasterCard Site Data Protection Program • American Express Data Security Operating Policy • Discover Information and Compliance • JCB Data Security Program
Payment Card Industry (PCI): Security Standards Council (SSC) “The PCI Security Standards Council is an open global forum, launched in 2006, that is responsible for the development, management, education, and awareness of the PCI Security Standards, including the Data Security Standard (PCI DSS), Payment Application Data Security Standard (PA-DSS), and PIN Transaction Security (PTS) Requirements.”
PCI SSC – Why? To help payment card industry organizations that process card payments prevent credit card fraud through increased controls around data and its exposure to compromise
PCI – Key players • Merchant • Acquiring Bank; Issuing Bank • Cardbrand • Service Providers • Council
PCI – Key players • QSA – Qualified Security Assessor • ISA – Internal Security Assessor • ASV – Approved Scanning Vendor • SAQ – Self-assessment Questionnaire • ROC – Report on Compliance
PCI - Founding Global Card Brands • American Express • Discover Financial Services • JCB International • MasterCard Worldwide • Visa IncAll have agreed agreed to incorporate the PCI DSS as the technical requirements of each of their data security compliance programs.
PCI Data Security Standard (DSS) • 12 Requirements – 250 Testing Procedures “PCI DSS provides a baseline of technical and operational requirements designed to protect cardholder data…”
Cardholder Data Environment (CDE) • The CDE is comprised of people, processes and technology that store, process or transmit cardholder data or sensitive authentication data. • The PCI DSS security requirements apply to all system components (any network component, server, or application) that is included in or connected to the cardholder data environment.
PCI DSS 2.0 - Overview V2.0 released October 28, 2010
